MySQL connection problem
 
I am trying to connect and administrate a mysql database through various programs (mySQL administrator, emma, mySQL navigator) but i keep having this message
"Could not connect to host "host name".
MySQL Error Nr. 1045
Access denied for user 'username@'vfppp079167045089.dsl.hol.gr' (using password: YES)

Click the 'Ping' button to see if there is a networking problem.


Now if I ping, the server is responding. By the way the port is 3306 but I' ve tried some other ports without any luck.
Could anybody help in any way. Thanks

Have you set up port forwarding?

wendle 09-26-2008 07:09 PM

Port forwarding in the wireless router you mean?

elprawn 09-27-2008 03:55 AM

Yeah, if you're trying to access outside the router then you have to forward port 3306.

Ok. I get it. BUT my stupid router hasn't got a port forwarding function. It only has a "FIREWALL RULES" with some predefined values (nothing about port 3306). The closest is the SQL-NET(TCP:1521) and another witch says ANY/ALL(TCP/UDP:1-65535). I checked the "allow" button next to them but still no luck!!!

Which router do you have?

wendle 09-27-2008 10:45 AM

Level1 Wbr-3460a

Is there no way of setting custom rules or do you have to choose from the list?

wendle 09-28-2008 10:55 AM

It has only some predefined values (nothing about port 3306). the closest that i can find is: ANY/ALL(TCP/UDP:1-65535).this is already turned on but still no luck

elprawn 09-28-2008 11:08 AM

Is that a rule for port blocking/allowing or port forwarding? i.e. does it ask you for a local address? Have you tried plugging your MYSQL server straight into the Internet rather than going through your router? (this way you could eliminate other possibilities).

Look for a setting called NAT maybe.

You might want to look for another router if you cannot find these settings. Or check into if a third party firmware like OpenWRT or DD-WRT support your router.

1. can you telnet to your box on 3306, firstly on localhost?

you should see something like this:

[09:59][root@server]/home # telnet localhost 3306
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
4
5.0.37@/kP0:tYB,}o5X;]CwPg8

2. what kind of a router/router version have you got? Normally if you've got those default values, there's an option to setup custom firewall/port rules where you select the port number, you name it whatever you like etc.
